SPECIFICATION forming part of Letters Patent No. 783,633, dated February 526, 1905.

Application iled December 2l, 1903. Serial No. 185,940.

To will whom, it 'rn/fry concern:

Beit known thet l, FREDERICK HAUT-MANN, a citizen of the United States, residing' et tdt. Peril, in the county ot' Ramsey and @tete olf Minnesota, have invented certain new and use- 'ful Improvements in Grain-Doors t'or Cars; nnd l do hereby declare the followingl to be a tull, clear, and exact description of the invention.v such es will enable others skilled in the art to which it nppertains to make and use the same. My present invention has lor its objectto provide a simple, cheap. strong', and durable `groin-door -tor railnniy-cars which is cnpzible ot quick and easy manipulation and which in all ways is ellieicnt for the purposes und in view.

.'.lo the above ends the invention consists of the novel devices and combinations et' dcvices hereinafter described, and delined in the claims.

The invention is illustrated in the eccompnnying' d rawings, wherein like characters indicate like parts throughout the several views.

Figure l is fr view in side elevation, showing' the central portion ot e beweer end showing one ot' my improved grain-doors applied thereto in working'position. Fig'. Qisatransvcrse vertical section tek-en :uiproximately on the line fr mi o'll Fig'. l. Fig'. 3 is a loi'ig'itudinal vertical section on the line f' ad of Fie'. 2; and Fig'. 4L is n view eorrespomling' to Fig. Q, but with the g'rniirdoor shown in nu elevated position by full lines and in n slightly-raised but operative position by dotted lines.

rl`he numernl l indicates the body ol the ilireight-czu', and the numeral 2 one ol the sidedoor (,)penings theri'eoi".

'lhe numeral 3 inilicntcs the main or lower section, and the immoral al the upper or supplemental section, ol'l the grain-door, which door-sections, respectively, hnve hinge mem bers 5 and (i. The hinge members 5 end o are pivotnlly connected, mid those near the edges ol the door are also pivot-elly connected to the lugs 7 ot' a pair of sliding' Ablocks d. These sliding' blocks 8 are mounted to slide vertically on supporting bars or rods Sk which bars, as shown, nre constructed ol [lat iron strips and are pivotnlly supported at their upper ends Afrom the overhead beam of the doortreme, being;l preferably rigidly secured to a transverse pipe or rod l0, which in turn is pivotnlly mounted in bearingbrackets ill on the seid overhezul beam. Also. pre teiably` but not necessnrily, the lower ends ol these bars nre rigidly tied together by a transverse pipe or rod 12. l`he sliding' blocks 8 ire provided with heavy hand-screws 13.y by meansoi which they may be rigidly secured in any desired vertical adjustment on the depending' bars or hnne'ers 9. 'lhe ends of the e'rainldoor sew tionsoverlap with the sides oi the door-'l'rame., as best shown in Fig. 23, to prevent them from, being' `lorced outward through the doorway under the pressure ol'l the lgrain Vlroln within. Un the l'loor oi'l the car at the doorway are slightly-raised retaining-lugs lli, which hold the lower portions ol the grailrdoor when in .its lowerlnost position close against the door-- tranne. To prevent the siunilemcntal door-sce tion il from being,` lorced inward when the grain-door is in its lowcrmest closed position, (indicnted in Figs. 2 and 3,) retniniiig-hooks lo are pivoted to the sides ol the door-trmie in position `lor eng'iug'ement with the upper edge ot the said door-section l, as shown in Fine 2 :ind 3.

To support the lgrain-door in :in elevated inu operative position close to the top ol the ozu'. as shown by l'ull lines in Fin'. fl, suspending hooks lli are pivoted to the transverse root-- beams ot the e: r-body. 'lhese suspending# hooks lo in their preferred construction enu gage with the. traniwerse tie-rod l2. whieh unites the liree ends ol the swinging' bars or hangers Si.

For most purposes thegrain-doormust have such l'ieig'ht that il made in a single section the two doors on thoopposite sidesol the ear when swungl upward to the root oll the ear would overlap with each other, and hence the :ulvisnbility or necessity ol the siuiplemeulal hinged door-sections- "ii/Vith the door constructed es described when it is desired to throw the seme upward into an inolwrative position (illustrated by lull lines in Fig'. fl) the sliding blocks il nre dropped to the lower ends of the swinging hangers 9, the ina-in door-section 3 1s turned on its hinge upward against the supplemental section 4 and in line with the i hangers 9, and then the whole folded door, including the hangers, is swung pivotally inward and upward into the said inoperative- In unloading' coal, grain, or some other ina-A terials it is desirable that the grain-door be supported in a slightly-raised position, so as to leave an opening only at the bottom vof the dooras shown, for instance, by dotted lines in Fig. 4:. As is evident, the grain-door supported as above described may be very quickly and easily set in this adjustment simply by forcing it upward and forcing sliding blocks 8 upward on the hangers 9. As is also evident, the grain-door may be supported in any desired operative vertical position by tightening the screws 13 onto the hangers 9, and thereby locking the blocks 8 thereto. If for any reason a grain-door when thus raised, or at any other time, for that matter. extends higher than is necessary or desirable, the supplemental section 4 may be turned inward and downward against the main section 3.

As is evident, the device above described is capable of modification within the scope of my invention as herein set forth and claimed. For instance, the door-hangers or suspending-bars, so called, might be round in crosssection instead of being flat and might be pivotally connected both to the car and to the 1 grain-door in a great many different ways.

However, the construction described has its important advantages and involves patentable features even in its details.

That I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. The combination with a car-body, having a door-opening, of a grain-door coperating with said door-opening, a pair of hangers pivoted to the upper portion of the car-body, a pair of blocks or brackets slidable on the free portions of said hangers and to which said grain-door is pivotally attached for folding.

'the car-body by a transverse rod 10, and tied at their lower ends by a rod 12, and the blocks 8 slidable on said hangers 9, provided with projecting lugs l connected with the hinges of said grain-door, said blocks further having f set-screws 13 for securing them on said hangers in any desired vertical adjustment, substantially as described.

In testimony whereof I atfix my signature in presence of two witiiesess.

FREDERICK HACHMANN.
